postinst fails: configure-symlinks missing even though mysql-common appears installed

[kibrom]

Ubuntu 16.04
mysql-server not successfully installed.

Output of the installation process in screenshot is below.

Plus: when I run the command ' sudo dpkg-reconfigure mysql-server-5.7 ' it says '/usr/sbin/dpkg-reconfigure: mysql-server-5.7 is broken or not fully installed'

From log:

Setting up mysql-server-5.7 (5.7.12-0ubuntu1) ...
/var/lib/dpkg/info/mysql-server-5.7.postinst: line 112: /usr/share/mysql-common/configure-symlinks: No such file or directory

Except that in the same log, previously, we see:

Thank you for taking the time to report this bug and helping to make Ubuntu better.

I don't understand how this could have happened. configure-symlinks is provided by mysql-common, and your log reports that it was installed before configure-symlinks was reported to not exist. /etc/mysql/conf.d is also provided by mysql-common and your report says that this is missing, too.

This makes no sense. Is there something broken about the mysql-common package on just your system?

I'm not sure that a developer can work on this without steps to reproduce, so I'm going to mark this bug Incomplete for now. If you can reproduce this, then please provide steps and then change the bug status back to New.

I am not sure on how to exactly describe the issue I am facing right now installing mysql-server, but this question on stackoverflow hints pretty much it.

Thank you for taking the time to report this bug and helping to make Ubuntu better. Reviewing your dmesg attachment in this bug report it seems that there is a problem with your hardware. I recommend performing a back up and then investigating the situation. Measures you might take include checking cable connections and using software tools to investigate the health of your hardware. In the event that is is not in fact an error with your hardware please set the bug's status back to New. Thanks and good luck!

I'm getting this too. Google is ranking this search.
 /usr/share/mysql-common contains only the "internal-use-only" directory.

We somehow had http://mariadb.mirror.digitalpacific.com.au/repo/10.2/ubuntu xenial/main amd64 as the source. (10.2.6+maria~xenial)

Commenting this out for "stock" 5.7.18-0ubuntu0.16.04.1 helped.
